Europe has lander goal for Mars
The European Space Agency mission, which would include a roving robot, would leave Earth in June 2011 and arrive at the Red Planet in June 2013.
The 500-million-euro mobile laboratory would "sniff" the air for signs of biology and listen to the ground for evidence of Marsquakes. Esa's last landing attempt, Beagle 2, went missing without a trace in 2003.
Top scientists and officials from the space agency (Esa) met this week to assess the best landing options. The workshop's ideas were presented to the media in London, UK, on Friday. They still require a great deal of further detail and the agency's member states will also have to sign off the mission. Ministers will have their say when the Esa Council meets in December
